[0045] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0046] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the embodiment of the utility model provides a photovoltaic connection device, comprising: two fixing components 1 and a connection component 2, the two fixing components are respectively connected to two adjacent photovoltaic floating bodies. The connection component 2 connects the two fixing components 1, so that the two adjacent photovoltaic floating bodies are connected.

[0047] In order to avoid rigid impact of the photovoltaic floating body during use, the fixing assembly 1 includes: a fixing plate 11, a connecting screw 12, a first spring 13, a locking nut 14 and a second spring 15. The fixing plate 11 is connected to the photovoltaic floating body by bolts. The connecting screw 12 is arranged on the side of the fixing plate 11 away from the photovoltaic floating body, and the connecting assembly 2 is sleeved on the connecting screw 12. The first spring sleeve is arranged on the connecting screw 12 and is located between the fixing plate 11 and the connecting assembly 2. The locking nut 14 is arranged at one end of the connecting screw 12 away from the fixing plate 11, and the second spring 15 is arranged between the connecting assembly 2 and the locking nut 14.

[0048] When in use, the photovoltaic floating body is set on the lake or sea surface. In order to avoid rigid impact between two adjacent floating bodies, a first spring 13 is set between the fixing plate 11 and the connecting assembly 2, and a second spring 15 is set between the connecting assembly 2 and the locking nut 14. When the wave hits the photovoltaic floating body, when the two adjacent photovoltaic floating bodies are close to each other, the first spring 13 and the second spring 15 are compressed, effectively resisting the wind and waves and eliminating the impact of the wind and waves on the floating structure, playing a role in protecting the floating body.

[0049] In one embodiment, if Figure 1 , Figure 2 and Figure 4 As shown, the connecting assembly 2 includes: two connecting plates 21 and a connecting rod 22 arranged between the two connecting plates 21. The two connecting plates 21 are sleeved on the connecting screws 12 of the two fixing assemblies 1, and the connecting plates 21 are located between the first spring 13 and the second spring 15 after installation.

[0050] During use, the connecting plate 21 contacts the first spring 13 and the second spring 15, and a relative force is generated between the two adjacent floating bodies under the action of the waves, so that the connecting plate 21 squeezes the first spring 13 and the second spring 15, causing them to deform to avoid damage to the connection between the floating body and the fixed plate 11.

[0051] In one embodiment, if Figure 1 , Figure 2 and Figure 3 As shown, the fixing plate 11 includes: a connecting portion 111 and two fixing portions 112 arranged on the connecting portion 111. The connecting screw 12 is arranged on one side of the connecting portion 111, and the fixing portion 112 is arranged on the other side of the connecting portion 111. A bayonet 113 for fixing the floating body is formed between the two connecting portions 111, and connecting holes 114 for connecting with the floating body are arranged on the two fixing portions 112. When in use, after the floating body is clamped in the bayonet 113, a bolt that matches the connecting hole 114 is selected to pass through the connecting hole 114, and then locked by a nut.

[0052] In one embodiment, in order to simplify the processing of the fixing plate 11, the fixing plate 11 and the connecting screw 12 are integrally formed.

[0053] In one embodiment, if Figure 3 As shown, since the fixing plate 11 is in contact with water, in order to prevent the fixing plate 11 from being corroded by substances in the water, an anti-corrosion layer 16 is plated on the outer side of the fixing plate 11. The anti-corrosion layer 16 is a protective layer formed after hot-dip galvanizing.

[0054] In one embodiment, if Figure 2 As shown, in order to prevent the first spring 13 and the second spring 15 from being unable to reset during use, spring stoppers 3 are provided at both ends of the first spring 13 and the second spring 15 .

[0055] It should be noted that the first spring 13 and the second spring 15 are made of weathering steel.

[0056] In one embodiment, if Figure 3 As shown, in order to improve the stability of the connecting device during use, there are four connecting screws 12 which are distributed on one side of the connecting plate 21 in a rectangular shape.

[0057] In one embodiment, in order to reduce the weight of the connecting device, the connecting screw 12 is a hollow screw.

[0058] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
